Tornadobrain

Based on game build 714014 | Last updated: 2026-02-27

Overview​

Tornadobrain is a brain component that defines the behavioral logic for tornado entities in Don't Starve Together. It inherits from Brain and constructs a behavior tree at startup. The behavior tree uses a priority node to select between two behaviors: Leash, which moves the tornado toward a specified target location, and Wander, which causes the tornado to move randomly in the vicinity of the target. Both behaviors rely on the KnownLocations component to resolve the target location by name. This component is responsible for enabling dynamic movement patterns, typically in scenarios where tornadoes chase or track a specific point of interest.

Components used: knownlocations Tags: None identified.

Properties​

No public properties are explicitly initialized in the constructor. The component stores its behavior tree instance in self.bt during OnStart().

Main functions​

OnStart()​

  • Description: Initializes and assigns the behavior tree for the tornado entity. Constructs a priority node that prioritizes leashing over wandering, then creates and stores a new BT instance.
  • Parameters: None.
  • Returns: None.
  • Error states: May fail silently if self.inst.components.knownlocations is missing or the "target" location is not registered, causing GetLocation("target") to return nil. This would result in undefined movement behavior (e.g., leashing/wandering to position \0``).

Events & listeners​

This component does not register any event listeners or push custom events. It operates purely as a behavior tree manager and does not interact with the event system directly.
